PFL MODE switch
In PFL mode (PFL MODE switch pressed, AFL MODE not pressed),
pressing an input channel Solo switch will send a pre-fade (pre-mute)
signal to the PFL bus and trigger the PFL monitoring in the master
section. This will override any AFL monitoring from the master sec-
tion AFL switches.

AFL MODE switch
In AFL mode (AFL MODE switch pressed, PFL MODE not pressed),
an input channel Solo switch will send a post fade, post pan signal to
the stereo AFL bus and trigger the AFL monitoring in the master
section. This will sum with any AFL monitoring signals selected in the
master section.
Solo in Place MODE
If both PFL and AFL mode switches are pressed then the monitoring
system is set for Solo in Place. If a Solo switch is pressed on any in-
put channel (mono or stereo input), all other un-pressed input chan-
nels will be muted. There is a SiP Safe switch on each stereo input
channel to inhibit the muting function.
The SiP system does not activate the monitoring circuitry in the
master section, so will not illuminate the PFL/AFL active LED by the
monitor meters, instead there are indicator LEDs in the meter-
bridge.
ADD MODE switch
Normally the channel Solo switches are exclusive—so they cancel any previously selected Solo switch. In
Add mode they do not cancel so more than one can be selected at a time.
SOLO CLEAR switch
Clears any active Solo switch. Illuminates when any Solo switches are active.
It is good practise to clear any Solo/Select switches before changing Solo MODE. This will
avoid any confusing selection if different switches are active in different modes.
Select MODE
If neither PFL or AFL mode switches are pressed, the mono and stereo input channel Solo switches operate
as MIDI select buttons. Further information about the MIDI functionality can be found on page 32.
